The YYTN (YTN) series is a line of shock-resistant (vibration-proof) pressure gauges designed for pressure measurement under pulsation, vibration and shock conditions. The gauge case is filled with damping fluid (glycerin or silicone oil) and fitted with buffer components, which absorb vibration and protect the precision movement — ensuring stable readings, reliability and a long service life.

Key features:

• Oil/glycerin-filled case — effectively dampens pulsation and mechanical vibration, keeps the pointer steady

• Accuracy class 1.6 (Class 2.5 available for 60 mm dials), dual-scale dials (MPa/psi or bar/psi) available

• Multiple dial sizes: 60 mm, 100 mm, 150 mm (YTN-60 / YTN-100 / YTN-150)

• Connection options: bottom (radial), back (axial) or flange mounting; G1/4, M14×1.5, G1/2, 1/4"NPT threads

• Material options: brass wetted parts with steel case, or all-stainless-steel (SS304/316) for corrosive media and environments

• Pressure ranges: from -0.1~0 MPa up to 0~100 MPa, custom ranges available

• Compliant with EN 837-1 / GB standards, CE and MC (CMC) certified options

Typical applications: hydraulic and pneumatic systems, pumps, compressors, machine tools, and pressure monitoring in metallurgy, power, petroleum, chemical, mining and light industry — anywhere with visible vibration or pulsating pressure.红旗仪表有限公司Alibaba.com
